DVD files added multiple times

Hi,

I am running 16.1 on a Wetek Core drawing files from a Synology NAS. When I scan my movie library it adds each individual DVD-ripped file as separate items. The files seem to conform to the required naming / folder structure; they are in individual folders. I have enabled the movies in separate folder option and recursive search.

If I move the files to a VIDEO_TS folder within their individual movie folder then the movie is, correctly, added once.

When I initially setup the library this problem didn’t occur. It was triggered by recreating the library after patching Kodi.

Is anyone else suffering from this issue?

Many thanks,

Tom
